mod: entrypoint for docker to setup db even in server with less memory

[TheSpiritMan]

Hello team,

• Modified File: packages/twenty-docker/twenty/entrypoint.sh

• Reason: The current entrypoint.sh works fine for server with RAM more than 8GB. But the server with less RAM will give error while running scripts/setup-db.ts.
  

• My commit: It will set NODE_OPTIONS="--max-old-space-size=8192" in docker entrypoint which guarantee to run the script successfully.

@TheSpiritMan According to :

• https://stackoverflow.com/questions/64119135/what-is-the-default-value-of-available-memory-when-max-old-space-size-flag-i
• https://stackoverflow.com/questions/48387040/how-do-i-determine-the-correct-max-old-space-size-for-node-js/48392705#48392705

To sum up :

• V8 computes the max-old-space-size to roughly 50% of the available memory if no parameter is passed to Node
• We consider that a common memory size for a VM is 2GB
• So we set it to 1.5GB
• We added a paragraph in the doc to put a system requirement at 2GB or more RAM
